[FIX] Windows 10 Update: Cisco VPN Client Removed

Windows 10 vs. Cisco VPN Client

Not what you're looking for? See my earlier post about Fixing Windows 10 after upgrading from Windows 7 or 8.

The saga of the incompatibility between Windows 10 and Cisco VPN Client v5.x continues on. After a rather pushy Windows Update, I reluctantly took the update and discovered that Windows was actually doing an upgrade to Version 1511, which took a while to complete. After waiting ages for it to install, I signed in and got a nasty little popup message that my Cisco VPN Client had been removed because it wasn't compatible (!!!!!). Game on.

TL;DR: Thanks to a Reddit thread on this issue, I was able to quickly find the final step to get everything working again.

Thanks to Reddit user AlphetaCS! I modified these steps slightly. Here's the original post.

  1. Download the vpnclient-winx64-msi- (not sure about x32 systems). This can be found online if you don't have it. One place that worked for me was the last file on this page.
  2. Use 7-Zip to extract the EXE file (we're going to need the vpnclient_setup.msi from the extracted files)
  3. Go to the Control Panel | Programs | Programs and Features, find the Cisco Systems VPN Client 5.0 in the list of programs, and use the repair option.
  4. The repair will ask you for an MSI source, point it to the extracted vpnclient_setup.msi in Step 2.
  5. At this point, if you try to connect you'll get a "Failed to Enable Virtual Adapter" error. This is where I left off, unsure of what to try next.
  6. To fix it, go to the Registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CVirtA and change the DisplayName value to "Cisco Systems VPN Adapter for 64-bit Windows" without quotes -- this entry typically has some crud before the display name that interferes with the driver.

Good luck!
